I'm an existing customer, what do I need to bring to open an account?

If you're an existing Commonwealth Bank customer you should simply bring with you (if applicable):

Existing Commonwealth Bank deposit account number(s)

Existing Commonwealth Bank debit/credit account number(s)

Pension type (Pensioner Security Accounts only)

Pension number (Pensioner Security Accounts only)

Please also bring with you your Tax File Number (TFN) or TFN Exemption if we don't already have it for your existing accounts. It’s not an offence to withhold your TFN for a deposit account. However, if you don’t quote it, the Bank is required by law to deduct tax from any interest earned on the deposit account, above a certain threshold.
